Orb of Shielding (Mabaran Obsidian)
Generic Variant, common (requires attunement)
An orb of shielding is a polished, spherical chunk of crystal or stone aligned to one of the planes of existence. If you’re a spellcaster, you can use this orb as a spellcasting focus.
If you’re holding the orb when you take necrotic damage, you can use your reaction to reduce the damage by 1d4 (to a minimum of 0).
